A pro-forestry activist pushing for workplace safety laws to be used against protesters entering logging coupes is frustrated an official investigation is taking so long.
"The Bob Brown Foundation have claimed responsibility for numerous protests in the past two years that have involved dangerous conduct that has endangered the lives of their staff, their volunteer protesters and others at risk," Kelly Wilton said.
"When will WST (WorkSafe Tasmania) apply the law equally?
"Will it take a death, and will they then own the fact that they have been aware of these issues and done nothing?"
Ms Wilton, who plans to run as an independent for the Legislative Council seat of Windermere, said she respected people's right to protest, and had taken part in some herself.
"Protesters have no place in dangerous work sites and organisations who are organising, facilitating and directing them are responsible for ensuring the safety of those involved.," she said.
She said she submitted a report to WST on Monday about a "notifiable incident" by the environmentalist Bob Brown Foundation during protests at a logging coupe.
Various protesters have been charged with trespass at the Tarkine coupe in recent days.
Some had chained themselves to forestry equipment and an access road gate.
Ms Wilton said a report of a notifiable incident involving the Bob Brown Foundation was raised with WST in April 2018.
"The BBF protesters had entered an operational logging coupe while harvesting was actively being conducted," she said.
"They were climbing over unsecured, freshly barked, slippery log piles that could easily collapse on the protesters, causing serious injury or death."
She said WST refused to take any action for months before then-premier Will Hodgman intervened and WST agreed to review the case.
She said she was told in October 2018 WST would initiate action against the foundation under state legislation and that it was the beginning of a full-blown investigation.
"The investigation is still ongoing," she said.
"Since that time, the BBF have continued to brazenly and publicly conduct protest and campaign actions that have involved dangerous conduct that constitute serious breaches of the Workplace Health and Safety Act."
She said it seemed clear WST had no appetite to act.
Bob Brown Foundation campaign manager Jenny Weber said no protesters had been injured through protests, but they had been violently attacked by loggers over the years.
"If the Tarkine is protected, there is no safety issue," Ms Weber said.
"It is the logging that creates the potential for harm.
"As with the Franklin campaign, those who saved the Styx Valley of the Giants, and all the great protests for human progress, the valiant people making a stand to save the Tarkine do so of their own volition."
Comment was being sought from the state government.
